A Probability Scale is a numerical value from 0 to 1 that measures the likelihood of the event(s).

Drag the movable points below to display how likely it was for the spinner to land on each color.

Probability is a type of ratio where we compare how many times an outcome can occur compared to all possible outcomes.

The Probability of an Event can be written as a ratio, decimal, or percent.

Theoretical Probability is what is expected to happen based on the possible outcomes, assuming equally likely events.

"What you expect to happen, but isn't always the case."

Experimental Probability is the result of an experiment or simulation after a large number of times.

"The probability determined from the results of an experiment."

Roll the die ten times and record the numbers in the table.

1st: Click "Reset" and count the number you see for Trial #1

2nd: press "Roll" to view Trials 2 - 10.

When you flip a coin there are only two possible outcomes. (Heads or Tails)

Say you flip a coin 10 times, theoretically Heads will appear 5 times.
